Application filed May 1, 1912. Serial No. 694,391.

To all whom 112} may concern:

Be it known that I, CHARLES WAGNER, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Junction-Box Covers; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in insulated junction-box coversand bracket connections for electric wall lights.

Its object is to make easy the installation of wall brackets so that abracket of any kind may be readily and easily attached by adjustabledevices whatever the angle at which the junction-box may have beeninstalled. By my invention the common insulating joint is dispensed withand there is no necessity, even in applying a narrow or unique backplate, to fill in the hole behind the plate as is necessary inordinarily placing such construction.

' In the drawings:-Figure 1 is a combined side elevation and verticalsection; Fig. 2 is a front elevation withthe bracket and lamp indicatedin dotted lines; Fig. 3 is a combined rear elevation and section; Fig. 4is a sectional plan view; and Fig. is a detail. I

In the drawings, 10 represents a wall and 11 a bracket to be securedthereto, which carries a connecting threaded pin '12 projecting from theinner Wall of the bracket.

, 13 is a ,junctiombox from the top and bottom of which lead conduitpipes 14, 15. f

16 and 17 are smaller and flexible conduits for the electric Wires 18,two sets being shown 'in this instance leading to the two lamp arms 19and 20, shown in dotted lines in Fig. 2.

Bent plates '21 are secured between the face-plate 22 ofthe-junction-box andplates 23 by bolts 24, there being suitable micainsulation, as indicated at 25.

At 26 is indicated an insulating division, preferably of mica, betweenthe bracket and the Wall, the space 27 being filled by the plaster ofthe wall.

The distinctive feature of each of the plates 21 is especially indicatedin the detail, Fig. 5, in. the slot 28 which has two pockets E29 and 30lying in different planes, for purposes hereinafter designated.

On the threaded end of the connecting pin 12 is screwed a nut 31 whichis held, in position by means of a set screw 32. On each side of the nutis a catch-pin 33 adapted to pass into the slot 28 and rest iii eitherone o1 the depressions or pockets, depending upon the position in whichthe face-plate is placed. In one position the pocket is farther backthan when the face-plate is in the other position, and thus there isprovided a slight :uljustnient depending upon the thickness of the wallto which it is applied.

The opening in the face plate a narrow opening in which part is cut. outand the other .parts slit and turned back to leave projecting lips 34,about which the plaster forming a part of the wall will be placedand'against which will lie the insulating backing 26.

In putting the bracket in place it is necessary to first decide uponwhat'position the plate shall have, that is which of the pockets shallreceive the pins, and then having ad'- justed the nut 31, to push in theconnecting pin 12 and the nut31 so that the projecting catch-pins 33pass into the slot 28 drop into I either the depression 29 or 30 as thecase may be. Thusby simply inserting and pushing down the bracket it issecurely placed, and may be readily removed.

My device may be applied to any junction-bor now in use.

I claim 1. In a junction-box, the combination with a cover, ofreversible plates in the j uncti0n-box and having securing devices indifterentplanes, and a pin projecting inward from the cover and havingadjustal'ile means for engaging the securing devices.

4 2. In a junction-box, the combinationwith a cover, of a pair ofopposing, slotted,

reversible plates, the slots having recesses in. different planes, and apin pro ecting 1nward from the cover and having adjustable catch-pinsfor engaging the. corresponding recesses in the slots of thereversibleplates.

3. In a junction-box, the combination with a cover, of a connecting,threaded pin, a nut borne by the pin,.catch-pins on the nut, and meanslying in difierent planes for plates having recesses in different planesto engaging the pins. I receive the catch-pins.
